Once the phone has been unlocked, we will see the home screen, and at the bottom, we will see a row of icons. It is in this area that we need to focus now because we need to open up the applications folder.

Press down on the top option, which says "Voice level" and underneath, "Normal"

.

This brings up a pop-up with the option to make the voice level louder or softer, depending on the situation. If we're in public, we might want to use a softer voice level. If we're driving or if there is a lot of noise, we might want to use a louder voice level to make sure we can hear what's happening and what's being said, to make sure we can hear the directions that are being given.

We can see that "Normal" is selected because the adjacent circle is blue. To change that, just press down on any one of the other options. We will press down on the word "Louder". Now it says the word "Louder" under "Voice level" in the "Navigation Settings" menu, indicating that we have successfully changed the voice level.
